Answer: 48 cm
Step-by-step explanation:
A perimeter(P) of a rectangle is equal to 2(L + W), or 2L + 2W, so we write the equation as:
1st way:
W = 50%(16) = 0.5 x 16 = 8
P = 2(L + W)
P = 2(16 + 8)
P = 2(24)
P = 48 cm
2nd way:
P = 2L + 2W
P = 2(16) + 2[50%(16)]
P = 2(16) + 2[0.5 X 16]
P = 32 + 2(8)
P = 32 + 16
P = 48 cm
